Bug 356323 – sys-devel/gcc-4.5.2: test failures in libmudflap

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description mehrunes 2011-02-24 18:07:49 UTC]

I tested gcc-4.5.2 on two computers, both amd64, one with AMD CPU, another with Intel

Results are very similar: count of unexpected failures for gcc/libstdc++/libmudflap is 7/18/48

> grep 'unexpected failures' 4.5.2_amd.log
# of unexpected failures        7
# of unexpected failures        18
# of unexpected failures        48



Reproducible: Always

Steps to Reproduce:
1. unkeyword sys-devel/gcc-4.5.2
2. FEATURES=test emerge =sys-devel/gcc-4.5.2
3.

Actual Results:  
some tests fail

Expected Results:  
tests successful

Since results are very similar, I only publish information from Intel box

emerge log

I wonder is it normal that core component such as gcc compiler or python fails tests?

Oh yes, very common.

The libmudflap fails look odd anyways.  Could you attach the .sum and .log files installed into /usr/share/doc.

libmudflap.log compressed

libmudflap.log is over 2M, so keeping files compressed

libmudflap.log from intel box, compressed

posts no. 4 and 5 contain files from AMD computer while previous posts contain information from Intel computer. 

Now correcting this and posting files from Intel computer:
 intel-libmudflap.log.lzma
 intel-libmudflap.sum.lzma

mudflap has been removed with gcc-4.9+ so we no longer track test failures in it
